Functional Notes
The following is a list of output messages from the
show interfaces shdsl
command:
Equipment Type Shows whether the unit is operating in CPE (NT) mode or CO (LT) mode.
Line Rate Shows the current line rate. The line rate is the data rate + 8 kbps.
Therefore, a rate of 2056 kbps implies an actual data rate of 2048 kbps.
Alarms Shows the current alarm conditions. Possible alarms are:
•LOS
LOSW - Loss of synchronization word (related to frame sync)
Loop attenuation (loop attenuation margin threshold has been
reached or exceeded; this threshold is user selectable and disabled
by default)
SNR margin (SNR margin threshold has been reached or
exceeded; this threshold is also user programmable)
CRC
Segment defect
Segment anomaly
Loop Status Shows additional information about the loop status as well as the
Embedded Operations Channel (EOC). Possible messages are:
SHDSL training complete (marginal signal quality). Establishing
EOC...
SHDSL training complete (marginal signal quality). EOC is up.
SHDSL training complete. EOC is down.
SHDSL training complete. EOC is up.
SHDSL training in progress.
Loopback State Shows the state of local and remote loopbacks. Possible local loopback
messages are:
Local dual-sided loopback
Local customer transparent loopback
Local customer non-transparent loopback
Local transparent network loopback
Local non-transparent network loopback
No local loopbacks
Possible remote loopback messages are:
Remote dual-sided loopback
Remote customer transparent loopback
Remote customer non-transparent loopback
Remote transparent network loopback
Remote non-transparent network loopback
No remote loopbacks
SNR margin Shows the current, minimum, and maximum signal-to-noise ratio of the
line. These may be cleared using the
clear counters shdsl
<slot/port>
command.
